Kai's verdictA-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
